Activated Carbon Filters Water Treatment

Discover the power of advanced water treatment solutions with our activated carbon and media filters designed for ultrafiltration in reverse osmosis pretreatment. Elevate your water purification processes, enhance system efficiency, and ensure superior quality. Explore our cutting-edge technologies for optimal results.



The role of carbon filter

Activated carbon is currently the most widely used adsorbent. It has micropores of various shapes in the middle of its lattice structure, forming a unique multi-porous structure,  which constitutes a huge adsorption area, so its adsorption capacity is particularly strong. 

Carbon filter adopts adsorption method to effectively remove organic matters, colloids, heavy metals in water, remove bad odors such as residual chlorine and reduce the color of water. It is widely used in water purification of factories and towns, as well as reverse osmosis, ultrafiltration and ion exchange The system's pretreatment process section and the water quality of various types of deep purification equipment.

Filtration principle:

       When the system is in the filtering state, when the water flows through the filter material layer, suspended matter is trapped by the filter material. The bottom of the filter has a water trap with a gap, and the filtered clean water flows out of the filter.

       Impurities are continuously accumulated in the filter material layer at any time. When the pressure difference increases to a certain set value or reaches the set cleaning, the system will automatically switch to the backwash state.
